Janesville Acoustics employees rejected the company's new contract proposal at a vote Tuesday afternoon.
"The last couple weeks, we've been negotiating items involving the plant closure and a severance package," said Casey Martin, union president.
Janesville management announced on Aug. 28 the closure of the Norwalk plant, putting about 300 workers, including hourly and salaried, out of work.
"As everyone knows, the company plans to phase out the Norwalk plant by the end of December 2014," Martin added. "The current contract is up Dec. 18, 2013 so we've been obviously trying to negotiate or extend something."
Martin said on Friday, the company made it's "last-final" contract offer.
